This drivingIpinion 12 drives a large gear'wheel 13 (see ig. 7) which is rigid with the pinion 14 that drives thelarge gear 'wheel 15. This large gear wheel is rigid with a pinion l6, meshing with a gear wheel 17 carried on a; horizontal shaft .18 which extends through the frame plate 11 to drive the totalizer mechanism 7 (see Fig This totalizer mechanism may be of any, suitable construction.

Th e details of thetotalif'zer mec anism are un-im rtantfbiifl substantially the i r hown iir'a prior application filed 'b Douglas Turner et 211., Serial No. 289,755. oweyen the construction should be such that been the clutch 'open the two number e l 5. d. as T i s mm to a r 'osition'. For this purpdsethe'number'w eel fi wliich is mounted loosely on the inner shaft 27 is rigidwith a 'laf'wheel 3Q iirhich meshes with a pinion 11 (see Fig. 2). This pinion 31 .is rigid heel 32 (see Fig. 11)

is;snch that by. the movement of a controlthat is cariied on a carrier shaft 33 supported on arms 34. These 'arnfis34 are all mounted ma ma-35 see Fig. 5) the ends of which are rotatab y .mohnt'ed in the end plates 28 and 29. On the face of the end plate'fl there is motinted a cam plate 36 vvhi'chis ri id with the 35 and the up per edge 0' this plate is for 'ried with a cam e 3 that is in position to en' age the proc ifig end of the inner shaft2 if the shaft 35 is rotated in a clockwise direction (see Fig. Then this. shaft is so rotated the cam edge 37 slidesth'e inner shaft 27 inwardly, that is to say, in a direction to open the clutch at 19,20. This rotation of the shaft 35 also eii'ects the return movement of the number wheels 5 andffi tozero. The carrying from the counter wheel 6 to the counter wheel 5 is effected by means of a Geneva disk 38 that is rigid with the number wheel 6 and cooperates with the Geneva stop wheel 82 (see Fig. ll). At each revolution of the counter wheel 6 the tooth on the Geneva disk 38 effects partial rotation of the stop wheel This rotation is imparted to the pinion 31, which in turn imparts its movement to the gear wheel and thereby rotates the number wheel 5 through one number space. In some machines it may be desired to use the outer face of the clutch member 20 as a number wheel and hence in this particular machine the wheel 20 is driven in unison with the pointer, 8 and at each revolution of the pointer 8 and the clutch member 20 a rotation is imparted through carrying mechanism 39 to the number wheel 6. This carrying mechanism 39 and the parts co-operating with it are substantially the same in construction as the arts described in connection with the eneva stop movement described above for carrying from the wheel 6 to the wheel 5. When the shaft is rotated in a clockwise direction and thereby opens the clutch, the arms 34 will swing away from the counter wheels and thereby disengage the carrier mechanisms from the counter wheels. The counter wheels are free to rotate on the inner shaft 27. A continued rotation of the shaft 35 in the same direction will eliect the return of the counter wheels to zero. In order in accomplish this each counter wheel is provided with a rigid heart-shaped cam 40and opposite each of these cams 40 there is'provi ed an arm 41 (see Fig. 11) each arm terminatin rig id with the shaft 35 but are each connected by a link 43 and spring 44 with acorresponding arm 34. Now when the arms 34 are swung away from the counterwheels'the points .42 come against the heart-shaped cams 40 and rotate the counter wheels around to their zero position.

The pointer S is also driven through a clutch of its own and I provide means in the form of a hand-operated member for simultaneously opening that clutch with the clutch composed of the members 19 and 20 and I also provide means actuated and moved by the hand-operated member for returning the pointer 8 to its zero position. These movements are all effected by means of a controling lever 45 which is pivotally mounted at 46 (see Fig. 4) on a frame plate 47 of the machine, and the lever may be operated from the exterior of the machine by means of a thumb plate 48. This lever 45 is bent into the shape of an inverted U and has a long arm 49 (see Fig. 4) which extends down into the interior of the machine. The lower end of this arm has a notch 50 which loosely engages a pin 51 on the side of a slide bar 52 which is mounted to slide longitudinally in the machine. From this slide bar l impart movement to the cam lever 36, referred to above. For this purpose the in a point 42. These arms 41 are not '100 a pressed construction'it will 'be'ev'i'dent that if the controlling lever'45ismoved in a downward direction (.see Fig. 10) the slide bar 52 will beslid toward the left as viewed in Fig. 5 and the cam plate 36 will be rotated in a clockwise direction with the effects described aboveii"Inbrder'toreturn the'slide bar 52 and the lever 45 afterthey have been operated I rovide acoil spring 56 (see Fig. 5)

one en of which is anchored to the vertical frameplatel'l and the other end of which is attached-to a trigger plate 57 which is pivotally mounted at 58 on theface of this plate '53, the lowerend o'f the trigger plate being provided with a downward projecting dog 59 as which engages the side of the pin 55 opposite to the aforesaid dog'54. By means of the trigger plate 57 thisspri'ng 56 not only performs the function of returning the slide "ways'fi'beflin engagement with the dog 54. Withfa construction "such as that described for" the totalizer it' is evident that the conitrollin lever 45 must 'be-completely dei'n'brder toeifect the return of the number wheels 5 and6 to'th'eir zero position'.--*Hence it is advisable to provide this machine with means for insuring that the items-11in" lever 45' will be completely dep re's'sed w enever it is operated. Without such ."a safety device a. careless operator mightfdepress'"the lever partially and open the clutch 19, 20 without returning the 'wh'eels5 and 6to,zero. I shall now describe "45 the safety devicewliich'I provide to insure the complete depression of the controlling lever'45.

i For this purpose the controlling lever is provided-with a segment 60 having ratchet bar 52'afterit has been operated but it also '30 holdsfthe lever 3650 that the pin will allever 45 from returning. Such a partial depression of the lever-45 is illustrated in Fig. 8. However, I construct these parts so that a complete depression of the lever 45 will effect the disengagement of-the point 64 from the teeth 61 and permit the lever 45 to return. For this purposel provide-the pawl 62 with an extension or tail 68 which projects upwardly and into the path of the lever 45 as it descends. r Fig. 8 it will be seen that any further downward movement of the lever 45 will effectl'a movement of the tail 68 by the lever 45'so=as to swing thepawl 62 in an anticlockwise: rection. This will disengage-the tooth 64 from the teeth 61 and will swing the pawl 62 far enough around to" enable a second notch 69 (similar tothe notch 67)' to be engaged by the pilot pawl 65. The-lever' 45willi then commenceits -upward' return movement through the clutch of the coil spring 56.

'moving up in this way"the'edge-of'the-segment will engage the side of the extension or tail 68 and just as the lever 45 arrives at its normal or inactive position: the segment will have returned the pawl 62 'to its rioruial position shown in Fig. 6. -:In'-this= way the segment 60 and thc'yieldinglyheld pawlioperate as a check device toeifctivelypreyent a partial depression ofthe controlling lever,

I shall: now'i-describerthe means whereby the movement ofthelslide bar 52 also operabesto open the clutch ofthe-'pointer Svand return'the ,same' to zero .ThepointerSis carried on" the upper end 'of ia. spindle/T0 (see Fig. 6)- whichfis-driven through bejvel gears 71 and 7 2, the former'aof whichisfrigid with the aforesaid :gear. wheel 15owhich is driven by the pinion '14.-

To drive spindle" 7O (see-Figs. 2' and 3) -.'there iSispIO- vided a clutch composed of an upper xelutch member 73 and a low'er clutch member? 74, the latter of which is constructed asi arloose collar on "a spindle 7 0,1 being -:not'rnally pressed upwardly against the Clllllih'tllllllher 73 by a coil spring 7 5. The=collarc76 of the clutch member 7 4 is engaged by a notch 77 inthe edge of. an actuating plate 178,

From an inspectlon of i 50 teeth 61 which areinclined (see Figs. 6 and 6O sothat its point'engages a notch 67 inthe the function of which is toopen 'theclutch. This plate is secured at.one*edge to a'rock shaft 79. One side of the plate 78. extends over to a point nearthe-slide. bar 52 atwhich point it has: an upwardly extending lug 80 carrying a small roller 81. 'Thisroller is adapted to be engaged by a cam :82 formed on'the under side of a plate 83 (see Fig. 3-) which plate 83 is rigidly-secured at 84 to the side of the slidehbar 52. Withthis construction it is evidentthat'if the-lslide bar 52 moves toward the right as viewed in Fig. 2, it will operate the clutch plate 78 to open the clutch. In order to efi'eot themeturn of the spindle 70* to zero I provide the same with two heartshaped-cams 85, and I 8)} Co-operating with this segment I providea'detent pawl 62 in the form of a plate pivoted at 63 on the frame plate 47 of the W machine. This'pawl plate 62 has a point 64 55 which normally engages the ratchet teeth 61 as shown in Figure 6. The pawl plate 62 is normally held in this position by means of a small pilot pawl 65 pivotally mounted on the 'plate 47 at 65 and pressed up by spring 66 edgeof the pawl plate 62. Now if the parts are in the position as shown in Fig. 6 it is evident that if the lever 45 is depressed. the point 64 of the awl 62 will maintain en- 65 ga'gement with the teeth 61 and prevent the also provide the under side of the plate 83 with two pawls 86 the points of which cooperate with the heart-shaped cams 85.

These paw-ls 86 are formed on a pawl plate 5 87 which is pivoted at 88 on the under side of the plate 83 and they carry a spring 89 which normally holds the pawl plate 87 against afixed stop pin 90. This spring 89 "enables the pawls 86 to yield slightly when they engage thecams 85 in returning the spindle 70 and its-pointer 8 to the zero posi- $1011.: Fig. 2 shows the parts in the zero position. At this time a shallow notch 91 formed in the edge of the clutch member 73 is engaged by theend of a detent pawl 92. .This pawjl pivoted at 93 (see Fig. 2) and .is provided-with a spring 94: which tends to hold-:theend of.the.pawl.a ainst the edge of the clutch member73. he function of 20 this-pawl is to stop the-pointer 8 exactly in its zero ition after it-has been returned to this-position; -In'Fig.- 2 the slide bar- 52 is rillustrated in'ia position displaced toward the right, as-iit; would be returning the pointer :8 =to zero. In this position the .clutch 19-20.would be'open; the clutch at '74 would also be 0 en. The-detent pawl 92 is then controlled yits spring 94 and will stopthe spindle 70 with the pointer 8 in the 30 zero position. However, when the slide bar 52 moves back toward the left as viewed ilgll 2:'and resumes itsi normal position it'gw' operate to disengage-the pawl 92 from 'the.notch; 91. =For this-purpose the plate-884s provided with a dog 95 that engages-the tail 96 extending from the pawl 92s The-tail v96 isimply .projectsinto the path-of'thisdog 95. (lo-operating with the measuring roller 9 there' is provided the usual 'presserroller indicateduat 97 (see Fig. 6) ;the details of which it isunnecessaryto illustrate 1 I'shallrnow describe the general mode of operation of the. machine. The fabric to be measured is drawn between the measuring ro1ler9 and-the-presserroller 97 and the movement ofthe measuring roller is imparted through the gear trains to the'pointer 8, through its'clutchmembers 73 and-74, and to the totalizing mechanism, through the shaft18 and 'the clutch members 19 and 20. The pointer B'cooperates' with its scale 3 to indicate yard "fractionsw At each complete revolution of the pointer 8 the units wheel 6 will be advanced through one number space so as to indicate the number of yards measured. At each complete revolution of the number wheel 6 the tens wheel 5 will be rotated through one number space. Hence the machine illustrated-will have the capacity of one hundred yards. In practice. however, it will be evident that a greater number of number wheels may be employed if desired-to give the machine a larger range or measuring capacity. After the complethe measuring rroller.

Lion of the measuring operation the pointer and the indicator wheels 5 and 6 may be returned to zero by simply depressing the controlling lCv'Cl l5. Depressing the controlling lever 45 operates through the extension 49 thereof (see Fig. 4:) to give the slide bar 52 a sliding movement. This 0peratcs through the plate 53 to move the clutch lever or clutch plate 36, the cam edge {37 of which (see Fig". engages the pro- JCCtlllg end of the shaft 27. This slidesthe shaft 27 and opens the clutch 19, 20. The clutch lever 36 is rigid with the shaft 35 (see Figs. 5 and 11) which carries the arms and All; therefore, the 5continued moven ent-of theshaft ina right hand direction uiscngages the carrying. mechanism from the number, wheels5' and 6 and the arms 4lenga 'c the .cams 40 of the. numberwheels in return .the same vto. zero. .Th slidmg movementpf the. slide; bar 52; operates through the. cam B2 (see effect .a downward.,.swin ingfllovement .of the clutch plate; '78 an ,thisfopensin-thelicluteh of the pointer-:8 .which is-coinposed oflthe sliding collar (at and the clutch member 73.
